IMPROVEMENI IN SAW-MILLS.

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom it may concern:

Be it known that I, DAVID G. GAY, of Eugene City, in the county ot' Lane and State of Oregon, have invented a. newnnd useful Improvement iu Sew Mills; and I do hereby declare that the following is :t full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

Figure l represents n side elevation of my improvement in saw-mills.

Figure 2 is zt plan view ofthe szune.

Simiiarlctters of reference indicate corresponding parts.

The object of' this inrention is io construct it new device for setting logs on thc vhezul-blocks of saw* mills.

I will first describe my invention, in connection with all that is necessary to :t fully understanding thereof, and then clearly point it out iu the'clztim.

.A in the drawing represents the carriage of the snwmill, resting on the iioor B of the mill, and supporting the head-blocks C, anda freine, D.

In each head-block is hung :t screw, E, which, when turned, will impart the desired longitudinal motion to the log on the head-block.

Each screw carries :t toothed wheel, ,Jnt end.

In the frame D nre hung two horizontal shnftsF 11, in line with each other, but ,not in direct connection, as shown in iig. 1.

its rear `can be carried to the right or left, so as to swing the wheel cl clear of'cither one ofthe wheels c. The motion can thereby be imparted to either one of the screws,to move either end ofthe loir` on the carringe.

A spring catch, e, serves to lock the lever' Hin either position.

Motion is imported to the wheel (l by suitable mechanism.

Having thus described my invention,

I ola-ini as new :md desire to secure byLettrs Patent-.-
